PAVEMENT. Y

Application lcd February 4, 1919. Serial No. v274;,877.

To aZZ w/iomz't may concern Be itY known'that I, PATRICK H. FARRELL, acitizen of the United Sta'tesof `American residing at Toledo, LucasCounty, Ohio, have inventedV new and useful Pavements, of which thefollowing is a specification.-

This invention relates'tofsectional pave- Y ments.

l This invention has'utility when incorporated inremovable sections ofblock pavement, especially as units adjacent special track work, as inintersections and switches.

VReferring to the drawings z- Fig.. l is a plan view of a trackintersection for street railways showing' in places units incorporatingfeatures of the invention therewith;

Fig. 2 is a perspective view of a fragmentary unit showing its mountingin relation to a rail;

Fig. 3 is a perspective view in fragment, showing the frame and portionsof the pavement section unit; and- Fig. 4 is a detail in Vsectionshowing the mounting of the unit in position.

The railway track is shown as a rail having` a ball l, upstanding webportion 2, and base flange 3. These rails may be mounted in position invarious ways as found desirable for instance, in ties, imbedded inconcrete. Y

rllhe pavementunit, in accordance with the invention herewith, mayconveniently comprise base supporting girders or planks 4, upon whichthe platform or base proper 5 may be lixedly mounted as by nails orbolts. YThis platform 5 of aY contour and dimensions desirable `for theinsertion of the unit especially between 'track sections, may carrythereon preferably wood paving blocks 6n which may be anchored theretoin spaced relation as to each other by nails 7 toe-nailed or driven atan angle through Vthe block sides into the pavement unit base portion5.Y These nails may be driven into the block from one'side only.

Integral lugs 8 Vmaintain theV blocks in spaced relation in theirgrain-up position, while the nailingvof the blocks in one side onlypermits of the expansion or adjustment of the blocks relatively to eachother on the v unit, base or platform. Bolts 9 through the overlappingjoist portions 10 of the edgewise disposed'plank members 1l mayeffectively anchor the frame or boardportions ll in the form of a frameabout the blocks 6 on the pavement base 5. This completed frame unit isaccordingly iii-position to be installed on the job according to thedimensions of the space to be filled thereby.

In the handling of pavements about track work, the pounding of trafficon the rails has aV Vdecided vtendency to disturb the rail foundationsand likewise the pavement. Unequ'al settling and working in of 'moisturewith the freezing or expansion tends to distintegrate the pavement, orthere is track trouble to be cared `for at various times necessitatingaccess to the track or rails for working with the foundation whichinvolves the taking up of the pavement, and in the usual mode of layingpavements by blocks or sheets, there is destruction or such a waste ofmaterial, that this repair problem is one involving?,v` considerableloss of time and material. In the provision of the unit, as hereindisclosed, such unit may be readily placed in position and will remainplaced as a goed and serviceable pavement unit. In the occasion Yofrepair for the base or for -care of the rails, this unit may be removedas a unit, and is not destroyed but may be placed back into positionwhen the repair work or investigation or inspection has had attention.V

This unit has a special utility or value when disposed between rails,but may to advantage be used adjacent rails or the special work, andtrack units for availing of this advantage of pavement unit removal andthereby avoid destruction of paving Iblocks in gaining access to thetrack or track ase.

The unit as to its base and frame may conform to the space in which itis to be installed, while it may be mounted upon the foundationsupporting the rails and the ties, it is preferably mounted in theposition to be carried by the flanges of the rails, especially on theside toward the rails. This means that the unit will be at all timesmaintainedl in position as to the rail.

In installing'the unit it has sufficient clearance as to the rail thatthe unit may be placed in position without difiiculty. When installedthis slight-space may be filled by crushed stone, or other desiredmaterials, which upon the removal of the unit may be taken out as foundconvenient.

In practice these units may be made up in the same manner that the tracksections are made up and shipped to the job for installation on thepavement base, thereby meaning a minimum of interruption of trafie inthe installation of the pavement. For

removal of the units, clearingl outY of a por` basel a track providedwith a rail having a flange integral therewith upon which flange .thebase rests on at least one side thereof whereby in track use settlingand recovery movement of the rail is followed by the blocks only as heldassembled on said base, thereby maintaining the blocks against relativedisturbance from rail movement.

2. The combination with a group of paving blocks, a plank baseVsupporting the blocks, andv a frame on the base maintaining the blocksin a pavement unit with Said base, ot a track provided with a railhaving a base flange engaged by the unit baseV whereby tratlie on therail tending to settle I the rail does not disturb the blocks of theunit as to the rail but such bloeks as as-V seinbled in theunit followthe rail inove-VV ment up and down. v

3. A pavement unit comprising la platform of parallel plank, transversestrips therebelow to hold the plank against relative settling, vwoodpaving blocks,4 nails anehoi'iiig the block in abutting relation to eachother on said platform, and a frame on said base about the blocks risingto the height of the blocks in completing"apavement Vwear against blockor frame shifting as to said platform. u

n witness whereof I affix my sig 3'natuie.
